## Section 2: Planning, design and installation

### 2.1 Cable/Connection hardware

Cable and connecting hardware used for campus communications installations must be of the type recommended by CTAG.

A central communications parts repository will be maintained by IST/Communications.

### 2.2 Horizontal cabling

Horizontal cabling is the portion of the telecommunications cabling system that extends from the work area telecommunications outlet to the horizontal cross-connect in the telecommunication room. The horizontal cabling includes the horizontal cables, the telecommunication outlet in the work area, and the horizontal cross-connect.

The maximum horizontal distance shall be 90 meters (295 feet), from the horizontal cross-connect in the telecommunication room to the work area outlet.

Work area components extend from the telecommunications outlet to the station equipment. Any special requirement in work area cabling (e.g. pair crossover) shall be done outside of the telecommunication outlet.

Each work area telecommunications outlet shall be connected to a horizontal cross-connect in the telecommunication room. A telecommunications room on the same floor should serve each work area.

A minimum of two telecommunications outlets shall be provided to each work area.

Always use suitable connecting hardware and equipment cables to make the connection to telecommunications equipment.

### 2.3 Backbone cabling

The purpose of vertical cabling (backbone cable) is to provide interconnection between telecommunication rooms, equipment rooms and entrance facilities. The vertical cabling consists of vertical cables and backbone cross-connects.

The use of UTP cable should be limited to a maximum distance of 90 meters (295 feet). See Appendix D for CTAG approved cable and connecting hardware recommendations.

### 2.5.1 Horizontal pathways

Horizontal pathways are the routes taken for the installation of cable from the telecommunications room to the work area. The pathways can be composed of cable tray, conduit, under floor duct, and ceiling spaces

### 2.5.2 Backbone pathways

Backbone pathways consist of conduit runs or risers going between floors, and are used to connect telecommunications rooms.

### 2.5.3 J-Hooks

J-hooks are to be used to support telecommunications cabling within ceiling spaces. They should be spaced (to a maximum) of approximately 4 feet apart. Cable pathways should follow a prescribed route going over top of heating ducts and other conduit if possible.

### 2.5.4 Telecommunication rooms, equipment rooms and entrance facilities

#### Telecommunication rooms

A telecommunications room serves a floor of a building and contains telecommunication equipment and cross-connects. A telecommunications room joins the backbone cable to the horizontal cabling system.

• All Telecommunications Rooms shall have direct access to the hallway or other such corridor. Telecommunications rooms shall not be shared by other building services such as Electrical (i.e. Electrical Distribution Panels or Transformers) or Custodial Services (i.e. Cleaning Carts, Solvents, Buffers). Either pose a threat of damage or EMF interference that makes them totally unacceptable for Telecommunications Equipment & wiring. Supporting codes are found in both BICSI TDMM & the TIA/EIA 568B wiring standard unequivocally against Multi-use Rooms.
• Telecommunications Rooms shall not contain any type of sink or be used as storage for Custodial or any other such supplies.
• Telecommunications Rooms shall not be used for storage of any kind. (I.e. Books, Furniture, A/C Filters, Light Bulbs, etc…)
• Floors in Telecommunications rooms shall be treated concrete or tile. Carpeted floors are totally unacceptable for Telecommunications Rooms due to the associated static electricity they create posing a threat of damage to sensitive Network Electronics.
• Each Telecommunications Room will have a minimum of three 4 in. sleeved core holes between floors. Empty core holes will be properly fire-stopped with intumescent fire pillows until they are needed.
• At least one long wall of a Telecommunications Rooms will be covered in ¾" fire rated plywood. From floor to ceiling. If fire rated plywood is not available then the plywood shall be painted with at least two coats of fire resistant paint.
• All Telecommunications rooms shall be equipped with a grounding bus bar that is tied back to the building’s grounding system.
• Telecommunications rooms that contain equipment or relay racks shall allow for 32" of open space on all sides of the rack.
• Telecommunications rooms must have adequate ventilation for the equipment that it houses.
• There must be adequate light
• Telecommunications rooms shall have a minimum of two duplex outlets.

#### Equipment rooms

An equipment room houses larger telecommunications or computer equipment. An equipment room may also contain the building entrance facilities and serve as a telecommunications room.

#### Entrance facilities

Entrance facilities are the location where telecommunication services enter a building.

### 2.6 Testing

UTP and fibre cable, both horizontal and backbone shall be tested in accordance with TIA/EIA-568-B.1

### 2.7 Building structure considerations

Guidelines to be followed:

• Under no circumstances shall any cutting of the structural parts of buildings, such as webs or concrete ceiling beams, be undertaken without prior approval of the Plant Operations Department.
• Plant Operations Department must first approve equipment installations in mechanical or electrical rooms.
• Smoke, heat or vibrations may activate fire alarm devices. Take precautions to ensure that an accidental alarm is not initiated.
• Cable shall be concealed in all finished areas such as offices, classrooms, labs and corridors.
• In accessible partitions, such as drywall, cables shall be fished through the partition to flush mounted outlets.
• In inaccessible walls, such as masonry or block walls, cables shall be concealed in raceway using appropriate raceway boxes and fitting.
• Wall outlets shall be mounted 300 mm above finished floor or 150 mm above existing desks or countertops. For general appearance, try to match the height of existing outlets.
• Provide sleeves where cables run through floors, ceilings or walls and firestop all sleeves.

### 2.8 Removal of obsolete cabling

Obsolete cable shall be removed. Care must be taken to avoid damaging any other cable that may be run in the same area as that cable which is to be removed. Records including type of cable, origin and destination of cable removed must be submitted to IST.

### 3.1 Records

All communication cabling works must be "as built" documented on practical completion. Copies of the logical diagrams, physical cabling layout and test results will be provided to the IST nominated Officer through their Faculty Technical Consultant or designate. Communications cabling shall not be used until it has been tested. All records and test results must be submitted to IST within two (2) business days of the completion of the job.
